[sdiy] PCB design advice

[Paul Schreiber]

I suggest looking at the MOTM pcb layouts at:

http://www.wiseguysynth.com/larry/motm/construct.htm

Which, IMHO, are the best example of how to lay out. Rules are:

20mil lines with 12mil spaces
100mil power traces
via size: 50mil/30mil hole
pad: most are 70mil with 40mil hole (40mil hole makes it easy to *unsolder*
mistakes). Some are 80mil pad.
LPI solder mask (this is key: you don't pay any more, and the end result is 10X
better than old-fashioned screened mask).
